+# Filamenteka Deployment Guide
+
+## Architecture
+
+Filamenteka now uses:
+- **Frontend**: Next.js deployed on AWS Amplify
+- **Database**: PostgreSQL on AWS RDS (publicly accessible)
+- **API**: Node.js server that can be run locally or deployed anywhere
+
+## AWS RDS Setup
+
+1. Navigate to the terraform directory:
+   ```bash
+   cd terraform
+   ```
+
+2. Initialize Terraform:
+   ```bash
+   terraform init
+   ```
+
+3. Apply the infrastructure:
+   ```bash
+   terraform apply
+   ```
+
+4. After deployment, get the database connection details:
+   ```bash
+   terraform output -json
+   ```
+
+5. Get the database password from AWS Secrets Manager:
+   ```bash
+   aws secretsmanager get-secret-value --secret-id filamenteka-db-credentials --query SecretString --output text | jq -r .password
+   ```
+
+## Running the API
+
+### Option 1: Local Development
+
+1. Create `.env` file in the `api` directory:
+   ```
+   DATABASE_URL=postgresql://filamenteka_admin:[PASSWORD]@[RDS_ENDPOINT]/filamenteka
+   JWT_SECRET=your-secret-key-here
+   ADMIN_PASSWORD=your-password-here
+   PORT=4000
+   ```
+
+2. Install dependencies and run migrations:
+   ```bash
+   cd api
+   npm install
+   npm run migrate
+   npm run dev
+   ```
+
+### Option 2: Deploy on a VPS/Cloud Service
+
+You can deploy the Node.js API on:
+- Heroku
+- Railway
+- Render
+- AWS EC2
+- DigitalOcean
+- Any VPS with Node.js
+
+Just ensure the `DATABASE_URL` points to your RDS instance.
+
+## Frontend Configuration
+
+Update `.env.local` to point to your API:
+```
+NEXT_PUBLIC_API_URL=http://localhost:4000/api  # For local
+# or
+NEXT_PUBLIC_API_URL=https://your-api-domain.com/api  # For production
+```
+
+## Security Notes
+
+1. **RDS Security**: The current configuration allows access from anywhere (0.0.0.0/0). In production:
+   - Update the security group to only allow your IP addresses
+   - Or use a VPN/bastion host
+   - Or deploy the API in the same VPC and restrict access
+
+2. **API Security**: 
+   - Change the default admin password
+   - Use strong JWT secrets
+   - Enable HTTPS in production
+
+## Database Management
+
+Connect to the PostgreSQL database using any client:
+```
+psql postgresql://filamenteka_admin:[PASSWORD]@[RDS_ENDPOINT]/filamenteka
+```
+
+Or use a GUI tool like:
+- pgAdmin
+- TablePlus
+- DBeaver
+- DataGrip
